The class that produced three perfect seasons in a row, with five once-in-a generation players, called "Generation of Miracles".
There was another player who all of them respected...
A legendary 6th player.
An up-and-coming power player, Taiga Kagami, comes to Seirin High School and meets the super-ordinary boy, Tetsuya Kuroko. Kagami is shocked to find that Kuroko isn't good at basketball! And he's so plain that he's impossible to see. But Kuroko's plainness lets him pass the ball around without the other team noticing him, and he's none other than the sixth member of the Generation of Miracles.
Kuroko makes a pact with Kagami to defeat the other members of Generation of Miracles, who have all played basketball at other schools.
A battle of light (Kagami) and shadow (Kuroko) begins!
